Yes indeed, the lenses are all metal. The point is, the newest Canon sensors are too sensitive for glass lenses. At ISO 1000000000 and above you would need a shutter time of a millionth of a second or faster. The simple solution is to make a titanium lens. With that and a recent sensor you can take lovely pictures of black cats in dark rooms. Success!

Cats are lazy & slow. A good camera should be able to take shots of black bats racing through dark caves, with the autofocus system & lens tracking the bats as they fly.
